摘　　要：用体积控制法对连铸结晶器弯月面区域的温度场进行了数值模拟，然后用鹿岛制铁所的一整套原始数据进行验证计算，计算输出为温度场分布、凝壳表面温度、凝壳厚度、渣圈形状、渣缝隙宽度等数值结果。温度场的进一步分析表明，弯月面部分凝固是铸坯表面振痕形成的根本原因。A model has been developed to compute temperature distribution in the vicinity of meniscus in CC mold with control volume method,and then a group of data of experimental continuous casting machine constructed at Kashima Steel Works is used to verify the mathematical models The calculated results include:temperature distribution,shell surface temperature,thickness of shell,the shape and size of slag rim,width of slag film After analyzing temperature distribution,the paper shows that partial solidification of meniscus is the basic reason for oscillation marks on strand
